确实变了，大概修改了一下：

package main

import (
    "fmt"
)

func main() {
    items := []int{1, 2, 3, 4}
    oddFirst(items)
    fmt.Println(items)
}

func oddFirst(s []int) {
    if len(s) < 2 {
        return
    }

    i, j := len(s)-2, len(s)-1
    for i >= 0 {
        if s[j]%2 == 0 {
            j--
        } else if s[i]%2 == 0 {
            temp := s[i]
            copy(s[i:j], s[i+1:j+1])
            s[j] = temp
            j--
            i--
        } else {
            i--
        }
    }
}
